Application filed October 25, 1906. Serial No. 340,468.

To aZZ whom it Wtwy concern:

Be it known that 1, JOHN W. ORROCK, of the city of Montreal, in theProvince of Q,ue bee. and Dominion of Canada, have invented certain newand useful Improvements in Traveling conveyer-Cranes, of which thefollowing is a full, clear, and exact description.

My invention relates to improvements in traveling conveyer-cranes forhandling coal, ore, grain, and the like.

The object of my invention is to provide a simple, inexpensive, andefficient conveyer which will require onlya small amount of motive powerand will operate under a variety of conditions. To accomplish thisobject, I provide a boot or hopper mounted on a truck adapted to travelon a suitable track. One end of a conveyer-mast is pivotally mounted inthe boot, and the other end is supported by a carriage running upon asuitable elevated rail. The upper end of the conveyer-mast is providedwith an adjustable hood and a pivotally-mormted deliverychute, intowhich a number of buckets, mounted on an endless chain, are discharged.

In the drawings, which illustrate my invention, Figure 1 is a sideelevation of the device in operation. Fig. 2 is a diagram showing thearrangement of tracks. Fig. 3 is a front view of the stock-pile bulkheadand shows the gates. Fig. 4 is a side elevation of the conveyer-boot andtruck.

Referring to the drawings, 1 designates the conveyer-mast, and 2 theboot or hopper mounted on a truck 3, running on a track 4. The trackmay, if desired, be sunk below the level of the surrounding ground inorder to assist in delivering material to the boot by gravity. Coal orore pockets 5 of the ordinary type are located on one side of the track4, while the stock-pile 6 is located on the opposite side. 7 designatesa train of cars on the track 8, located adjacent the track 4, from whichthe material to be delivered is discharged. An endless chain carryingthe buckets 9 runs longitudinally over the conveyer-mast l and ismounted thereon in the usual manner, said chain being driven by a smallmotor or any other suitable power device 10. The asoending buckets passinto a hood 11 and discharge their contents into a chute 12, pivotallymounted at 13, so as to be angularly adjustable with respect to thecarriage 14, which travels on the track 15, mounted on the coal-pockets5. When it is desired to discharge material to the stockpile 6, thewhole conveyer is moved along the track 4 onto the turn-table 16 andturned around to occupy the position shown in dotted lines in Fig. 1,the carriage l4 traveling on the semicircular portion 17 of the track15. The boot 2 is supplied with material through the chute 18 from thecars 7 or through the chute 19 from the stock-pile 6. Engines, cars, orany other receptacles standing on the track 20 may be readily suppliedwith material through the. adjustable chutes 21, mountedon the pockets5, while the track 22 may be used for storage purposes.

A tightener 23 is fixed to the upper end of tiile mast for taking up theslack in the bucket- 0 am.

The stock-pile is built up behind a bulk- 4 head 24, provided with gates25 for admitting the coal to the chute 19. If the source of power 10 bean electric motor, its current may be taken from storage batteries orfrom a trolley-rail 26, located below the rail 15, by means of a trolley27. l

The operation of the device is as follows: Material of any kind may befed from the car 7 or from the stock-pile 6 into the boot or hopper 2and carried by means of the buckets into the pockets 5. When it isdesired to store material in the stock-pile, the conveyermast is swungaround to the position shown in dotted lines by means of the turn-table16 and the buckets fed from the cars 7. The whole conveyer may be movedalong the track 4 to load any part of the stock-pile or any one of thepockets.

The advantages of this device are numerous and will be readilyappreciated by those skilled in the art of handling coal, ore, grain, orthe like.

Having thus described my invention so that the same may be readilyunderstood by those skilled in the art to which it appertains, what Iclaim, and desire to secure by Letters Patent, is

1. In a conveyer device, the combination with a surface track of a truckmounted thereon, a boot or hopper mounted on said truck, a mast carriedby said boot, an elevated track, 'a carriage supporting the upper end ofthe mast upon said elevated track, means for delivering material intoboth sides of said boot or hopper, and a bucket-chain adapted todischarge said material from the upper end of the mast.

2. In a conveyer device, the combination with a track of a truck mountedon said track, a boot carried by said truck, a mast a mast carried bmounted on said boot, an endless bucketchain traveling over said mast,and means for discharging material upon both sides of said track.

3. In a conveyer device, the combination with a track of a truck mountedon said track, a boot or hopper carried by said truck, said boot, anendless bucket-chain trave ing over said mast, a carriage supporting theupper end of said mast, means for driving said bucket-chain, and meansfor discharging material upon both sides of said track.

4. In a device of the class described, in combination with a series ofpockets, a stockpile, and a track located between said pockets andstock-pile, a conveyer-boot running on said track, means for supplyingmaterial to said boot, and means for alternately discharging materialinto said pockets and stockpile.

5. In a device of the class described, the combination with a series ofpockets, a stockpile and a track located therebetween, of aconveyer-boot traveling on said track, means for supplying material tosaid conveyer-boot, a mast pivotally mounted upon said boot, abucket-chain traveling over said mast, means for driving saidbucket-chain, and means for delivering material alternately to saidpockets and stock-pile.

6. In a coal or ore handling device, a series of pockets, a stock-pile,a depressed track therebetween, a conveyer-boot traveling on said track,a mast pivotally mounted in said boot, an endless bucket-chain mountedon said mast, means for delivering coal or ore to said boot, a tracklocated above said pockets and stock-pile, means for supporting theupper end of said mast upon said track, and means for deliveringmaterial alternately to said pockets or stock-pile.

7. In a coal or ore handling device, a series of pockets, a stock-pile,a depressed track therebetween, a conveyer-boot traveling on said track,a turn-table in said track, a mastpivotally mounted in said boot, anendless bucket-chain mounted on said mast, means for delivering coal orore to said boot, a track elevated above said pockets and stock-pile,means for supporting the upper end of said mast upon said track, andmeans for controlling the supply of material from said stockpile to saidboot.

8. In a coal or ore handling device, a plurality of pockets, astock-pile, an elevated track connecting said pockets and stock-pile, asecond track located between said pockets and stock-pile, a truckrunning on the second track, a conveyer-mast carried by said truck, andmeans for operating said conveyer to discharge material into either thepockets or the stock-pile.

In witness whereof I have hereunto set my hand in the presence of twowitnesses.
